Definitions

  • This patent concerns household appliances for floor cleaning and in particular it concerns a new steam broom for floor cleaning with adjustable steam jets underneath and/or at the front and with detergent mixing.
  • Several types of household appliances for floor cleaning are known, which can be used in private, public or commercial buildings. Electric brooms and vacuum cleaners are known that, in addition to sweeping, take the impurities in, which are collected in suitable bags and then disposed of as waste.
  • the large floor cleaners that are used in large places such as public or commercial buildings perform both functions of collecting waste by sweeping the floor and sucking in the waste and cleaning and washing by means of suitable brushes and jets of detergent or steam.
  • These appliances are extremely versatile and can guarantee excellent results in term of cleanliness but they are cumbersome and their use in homes is therefore totally unthinkable.
  • the known household appliances for floor cleaning do not often have the same versatility, thus making it necessary to use several different tools for sweeping, washing and polishing.
  • the main task of this invention is to provide deep and complete floor cleaning.
  • a further purpose of this invention is to clean floors by using steam and/or a detergent.
  • a further purpose of this invention is to be handy and easy and safe to use.
  • Said new steam broom for floor cleaning comprises among its main parts a boiler for steam production and devices for the transport and delivery of steam jets and detergent and for the control of the boiler pressure.
  • the new steam broom comprises a main body, which contains the boiler for steam production.
  • Said boiler is a metal tank comprising at least one heating element connected to a special circuit so that the connection to the mains causes the heating of said heating element and the consequent heating of the water contained in the boiler.
  • the boiler comprises special temperature and/or pressure gauges that guarantee its safety by enabling the opening and closing of the electric circuit powering the heating element according to the pressure reached by the steam and they therefore have the task to control and adjust, if necessary, the pressure level most suitable for the cleaning.
  • the boiler comprises further safety systems, i.e. valves and devices that guarantee its safe use by the user.
  • the opening and closing of the valve responsible for steam output from the boiler is controlled by a special device, hereinafter called operating device.
  • Said operating device is connected to one of the arms of the lower fork of the handle of the new steam broom so that it is necessary and sufficient to operate said handle to cause the boiler to deliver the steam.
  • the operating device is positioned in such a way that steam delivery is allowed by simply slanting the handle from the vertical position of rest to the oblique position towards the user.
  • the device When the user slants the handle in the right direction, said device is then operated and it causes the opening of the output valve and the delivery of steam as a consequence.
  • the device can be for example a cam insisting on the steam output valve, which opens when the handle is moved from its vertical to its slanting position, thus causing the simultaneous displacement of said device.
  • the delivery of steam is interrupted when the handle is moved back to its vertical position.
  • Such rotation of the handle from the vertical to the slanted position causes moreover the closing or opening of a switch that connects or disconnects the heating element to or from the power supply circuit, while bypassing the main temperature and/or pressure gauge that is set at a pre-set temperature and/or pressure value.
  • the heating element is immediately powered so that during the delivery of steam the entire system can keep a sufficiently high pressure so as to guarantee an excellent cleaning efficiency.
  • the output duct from the boiler shall then comprise a fork to allow the steam delivery from several points of the main body of the new steam broom, i.e. from one or more nozzles located in a front position for steam jet at the front, and/or one or more nozzles located in a lower position for downward steam jet, namely directly towards the floor.
  • the output duct from the boiler is therefore connected to at least two delivery ducts, the one taking the steam to the front nozzles and the other taking the steam to the nozzles located under the main body.
  • Said ducts are hereinafter called duct for steam delivery for front jets and duct for steam delivery for lower jets respectively.
  • a device hereinafter called a device for jet deflection, has the function to open or close said delivery ducts to allow the steam to come out from the front and/or lower nozzles.
  • said device for jet deflection is for example a slider that, if moved from a set position to the other one, can compress the duct for steam delivery for front jets or the duct for steam delivery for lower jets, thus causing the shutting of a delivery duct and therefore interrupting the steam delivery from the nozzles linked to that specific duct.
  • the device for jet deflection is positioned so as to shut neither of the two ducts for steam delivery for front jets and for lower jets.
  • the new steam broom comprises a further delivery duct, hereinafter called detergent delivery duct, which is connected to a special cup containing the floor detergent and located in a suitable position inside the main body.
  • the device for jet deflection can be positioned so as to shut only the duct for detergent delivery, in case the user does not want to use the detergent but only steam.
  • the delivery ducts are made of a silicone hose and are deformable so that they can be easily compressed by the action of said device for jet deflection and can then go back to their initial shape.
  • the duct for detergent delivery is provided with a fork that connects it both to the duct for steam delivery for front jets and to the duct for steam delivery for lower jets.
  • the link between the duct for detergent delivery and each of the two ducts for steam deliver is obtained by means of a Venturi tube, i.e. a reduction of the section of the duct for steam delivery for the jets and when the steam meets such reduction, its speed increases, thus causing a depression in the duct for detergent delivery.
  • the detergent is sucked into said duct for steam delivery so that it can come out of the front and/or lower nozzles already mixed with the steam.
  • Figure 1 shows an overall view of the invention.
  • Figure 2 shows a section plane of the new steam broom, where it is possible to see the delivery ducts, the arrangement and functioning of the jet and pressure operating and controlling devices.
  • FIG. 3 shows detailed schemes of the different possibilities of steam and detergent delivery by changing the position of the device for jet deflection.
  • the main body (S) is connected to the handle (M) by means of a fork with two arms (Ml) and (M2) that are hinged on the main body (S) by means of special hinges (M') and (M").
  • Said main body (S) comprises nozzles (Gf) and (Gi) located in the front part, the tip, and in the lower part respectively.
  • the main body (S) contains the boiler (C), which comprises an input hole
  • Said boiler (C) hosts a heating element (R) inside and when appropriately connected to the mains through a normal circuit, it begins to function, thus heating said heating element (R).
  • a primary temperature gauge (Pl) and/or a pressure gauge located inside the boiler (C) and connected to the circuit for power supply to the heating element (R) has the task to check the pressure level of the steam produced and contained inside the boiler, thus causing the opening of the electric circuit whenever the temperature and/or the pressure reach the limit value at which Pl is set.
  • the safety valve (Vs) provides for the safe use by the user by allowing the steam delivery in case that the pressure inside the boiler reaches dangerously high values.
  • Said output duct (Cu) is shut by an output valve (Vu), which is opened by a specific operating device (Da).
  • Said operating device (Da) is connected to arm (Ml) of the handle (M), so that the rotation of said arm (Ml) around the hinge (M') causes the displacement of said operating device (Da), thus causing the opening of the output valve (Vu).
  • the boiler (C) comprises a further temperature gauge and/or a pressure gauge, hereinafter called secondary gauge (P2), which is set at a temperature and/or pressure value that is higher than the temperature and/or pressure value Pl.
  • secondary gauge P2
  • a switch (Dp) connects the mains to the heating element (R) while bypassing the primary gauge (Pl), so that the circuit can be immediately closed as soon as arm (Ml) or (M2) of the handle (M) is moved to a slanted position, i.e. to position ⁇ .
  • Said switch (Dp) is linked to arm (M2) of the handle (M), so that the rotation of said arm (M2) around the hinge (M' ') causes the opening and closing of the same switch (Dp), thus allowing the connection of the heating element (R) to the electric circuit powering the same heating element (R).
  • the output duct (Cu) is connected to at least two steam delivery ducts: the duct for steam delivery (Cf) for front jets and the duct for steam delivery
  • the duct for detergent delivery connects the cup (Sd), which is the detergent tank, to both ducts for steam delivery (Cf) and (Ci) for front and lower jets.
  • connection between the duct for detergent delivery (Cd) and each of the two ducts for steam delivery (Cf) and (Ci) for the jets is obtained by means of Venturi tubes, i.e. reductions (TVf) and (TVi) of the sections of the ducts for steam delivery (Cf) and (Ci) for the jets.
  • Venturi tubes i.e. reductions (TVf) and (TVi) of the sections of the ducts for steam delivery (Cf) and (Ci) for the jets.
  • the device for jet deflection (D) is a slider that can be moved from one set position to the other, as shown in Figure 3, in order to prevent/allow the delivery of steam from the front nozzles (Gf) and/or the lower nozzles (Gi).
  • the intermediate positions D2 and D4 allow shutting the duct for detergent delivery (Cd) at the same time as the duct for steam delivery (Ci) for lower jets or the duct for steam delivery (Cf) for front jets respectively.
  • Shutting one or more delivery ducts entails the interruption of steam and/or detergent delivery from the nozzles linked to those specific ducts.
